## Prestressed Concrete Handwritten Classroom Notes for Gate PDF

To indicate that a member force is in tension, we draw the force vector pointing away from the joint, along the centre line of the member.  Actually, we don't really need to know the angle itself; rather, we only really need to know the sine and cosine of the angle—sinθ and cosθ. We can apply the Pythagorean.

The negative magnitude of FAI ensures that it is mathematically represented as a compression force. It is important to note that both angles label as θ on the free body diagram is exactly the same as the angle θ on the diagram of Joint A.

(If you can’t see that these angles are all equal, prove it to yourself by drawing the corresponding right triangles, just as we did for Joint A.) . If we begin with the equilibrium equation in the y-direction, we will be able to solve for FCI directly.
